Description

Technical Field

[0001] The present application relates to the field of fixing devices, and in particular to a fixing device. Background Art

[0002] Quilts are a necessity in people's lives, and are generally composed of a quilt core and a quilt cover. The quilt cover is generally opened at the foot end or at the side, and a zipper is provided to facilitate the insertion of the quilt core. Since the quilt will be pulled and deformed by the user during use, the matching degree between the quilt core and the quilt cover decreases. With the development of society, in order to improve the quality of life, a fastener has appeared. A fastener is a fixing device used to relatively fix the quilt cover and the quilt core, and it mainly has the functions of preventing the quilt from running away, preventing the quilt from slipping, and preventing wrinkles.

[0003] The fastener in the related art includes a fastening buckle and a fastening nail. When in use, the user first arranges the quilt to be fixed, then inserts the fastening nail into the appropriate position of the quilt, aligns the fastening nail with the small hole at the bottom of the fastening buckle, and inserts the fastening nail into the small hole with a little force. The locking device in the fastening buckle can lock the fastening nail, thereby achieving relative fixation of the quilt cover and the quilt core.

[0004] However, when the quilt cover and the quilt core are fixed by the above-mentioned fixing device, the fixing nails need to pass through the quilt cover and the quilt core, resulting in the fixing nails causing damage to the quilt cover and the quilt core, which is obviously insufficient. Summary of the invention

[0005] In order to improve the problem that the quilt cover and quilt core may be damaged when the fastener is used, the present application provides a fastener.

[0006] The present application provides a fixator that adopts the following technical solution:

[0007] A fixer comprises an upper fixing buckle and a lower fixing buckle, a quilt cover and a quilt core are arranged between the upper fixing buckle and the lower fixing buckle, and a locking mechanism for locking is arranged between the upper fixing buckle and the lower fixing buckle.

[0008] By adopting the above technical solution, the upper fixing buckle and the lower fixing buckle are locked by the locking mechanism, so that the upper fixing buckle and the lower fixing buckle can fix the quilt cover and the quilt core relatively, reducing the possibility of the fixing device causing damage to the quilt cover and the quilt core. The present application has the advantage of reducing the possibility of the fixing device causing damage to the quilt cover and the quilt core through the arrangement of the upper fixing buckle, the lower fixing buckle and the locking mechanism.

[0009] Optionally, an upper bite strip is connected to a side of the upper fixing buckle facing the lower fixing buckle, and a lower bite strip is connected to a side of the lower fixing buckle facing the upper fixing buckle.

[0010] By adopting the above technical solution, the upper bite strip and the lower bite strip cooperate to achieve the bite of the quilt cover and the quilt core, reducing the possibility of the quilt cover and the quilt core being pulled out from between the upper fixing buckle and the lower fixing buckle when the locking mechanism is in the locked state.

[0011] Optionally, the locking mechanism includes a fixing pin connected to the lower fixing buckle, a cavity opened on the side of the upper fixing buckle facing the lower fixing buckle, an outer lock cylinder connected to the cavity, and an inner lock cylinder arranged in the outer lock cylinder, the fixing pin, the outer lock cylinder and the inner lock cylinder are coaxially arranged, the diameters of the inner lock cylinder and the outer lock cylinder gradually decrease along the direction from the upper fixing buckle to the lower fixing buckle, and at least two accommodating openings are circumferentially opened on the outer side wall of the inner lock cylinder, the accommodating openings are communicated with the inner cavity of the inner lock cylinder, a clamping piece is provided in the space between the accommodating opening and the inner side wall of the outer lock cylinder, a shifting opening is opened on the upper fixing buckle, the shifting opening is communicated with the cavity, a shifting block is slidable in the shifting opening, and one end of the shifting block extends into the cavity and is located below the inner lock cylinder.

[0012] By adopting the above technical solution, when locking, the fixing nail is inserted from the bottom end of the inner lock cylinder, and the fixing nail drives the inner lock cylinder to move in the direction away from the lower fixing buckle through the clamping member. After the fixing nail is inserted into the inner lock cylinder for a certain length, the user separates the upper fixing buckle and the lower fixing buckle in the reverse direction, and the fixing nail pulls the inner lock cylinder to move in the direction close to the lower fixing buckle through the clamping member. However, since the diameters of the inner lock cylinder and the outer lock cylinder gradually decrease from the upper fixing buckle to the lower fixing buckle, the inner lock cylinder can only move a very small amount, and the fixing nail will also be clamped between the three clamping members.

[0013] Optionally, the clamping member is a ball.

[0014] By adopting the above technical solution, the fixing nail is clamped in a point contact manner.

[0015] Optionally, the clamping member is a columnar locking column, and the axis of the locking column is parallel to the line between the upper fixing buckle and the lower fixing buckle.

[0017] Optionally, a compression spring is provided in the cavity, one end of the compression spring supports the top wall of the cavity, and the other end of the compression spring supports the inner lock cylinder.

[0018] By adopting the above technical solution, the supporting effect of the compression spring on the inner lock cylinder reduces the possibility that the inner lock cylinder moves relative to the outer lock cylinder, causing the locking mechanism to loosen accidentally.

[0019] Optionally, a receiving cavity is provided on the lower fixing buckle, and anthelmintic pills are placed in the receiving cavity. A sealing cover is detachably connected to the opening of the receiving cavity, and a plurality of air holes are provided on the sealing cover.

[0020] By adopting the above technical solution, the anthelmintic pills can emit odor, and the odor is transmitted to the outside of the accommodating cavity through the air holes, thereby achieving the purpose of anthelmintic.

[0022] By adopting the above technical solution, when the user locks the upper and lower fixing buckles, the plug-in strip is inserted into the tooth cavity, and the elastic member supports the rotating strip, so that the rotating strip drives the teeth to rotate, and the teeth on the rotating strip can be inserted into the tooth grooves on the plug-in strip, thereby achieving the locking of the upper and lower fixing buckles. When the user needs to unlock the upper and lower fixing buckles, the key is inserted into the lock hole and the key is turned, and the dial on the key can drive the rotating strip to rotate, and the rotating strip drives the teeth to disengage from the tooth grooves, so that the upper and lower fixing buckles can be separated.

[0023] Optionally, the elastic member is a V-shaped spring sheet, one side of the spring sheet supports the rotating bar, and the other side of the spring sheet supports the inner wall of the lock cavity.

[0024] By adopting the above technical solution, the supporting effect of the spring sheet can achieve the matching of the teeth and the tooth grooves.

[0025] Optionally, a fixing block is connected to the side wall of the lock cavity, and a "V"-shaped limiting groove is formed in the fixing block relative to the "V"-shaped tip of the spring sheet, and the "V"-shaped tip of the spring sheet is inserted into the limiting groove.

[0026] By adopting the above technical solution, the limiting groove has a limiting effect on the spring sheet, thereby reducing the possibility of the spring sheet tilting and twisting during deformation, which may cause adverse effects on the top support of the rotating bar.

[0027] To sum up, the present application includes the following beneficial technical effects: using a locking mechanism to lock the upper fixing buckle and the lower fixing buckle, thereby achieving relative fixation of the quilt cover and the quilt core by the upper fixing buckle and the lower fixing buckle, which is beneficial to reduce the possibility of damage to the quilt cover and the quilt core caused by the fastener.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-8 This application is described in further detail.

[0039] The embodiment of the present application discloses a fixer.

[0040] Example 1

[0041] Reference Figure 1 The fixing device comprises an upper fixing buckle 1 and a lower fixing buckle 2, the quilt cover and the quilt core are clamped between the upper fixing buckle 1 and the lower fixing buckle 2, and a locking mechanism for locking is provided between the upper fixing buckle 1 and the lower fixing buckle 2. The upper fixing buckle 1 and the lower fixing buckle 2 are locked by the locking mechanism, so as to clamp the quilt cover and the quilt core, and reduce the possibility of the fixing device causing damage to the quilt cover and the quilt core.

[0042] Reference Figure 2 and Figure 3 The upper fixing buckle 1 includes an upper buckle seat 11 and an upper buckle cover 12 bolted to each other, and the lower fixing buckle 2 includes a lower buckle seat 21 and a lower buckle cover 22 bolted to each other. When the locking mechanism is in the locking state, the quilt cover and the quilt core are clamped between the upper buckle cover 12 and the lower buckle cover 22. The lower buckle seat 21 is provided with a plug-in slot 3 for the upper buckle seat 11 to be inserted into. The setting of the plug-in slot 3 plays a role in limiting and guiding the upper fixing buckle 1.

[0043] Reference Figure 2 and Figure 3 When the locking mechanism is in a relaxed state, part of the upper buckle seat 11 is still located in the insertion groove 3, thereby reducing the possibility of relative rotation between the upper fixing buckle 1 and the lower fixing buckle 2. At the same time, when the locking mechanism is locked or unlocked, the relative movement between the upper fixing buckle 1 and the lower fixing buckle 2 plays a guiding role.

[0044] Reference Figure 2 and Figure 3 The lower buckle seat 21 is integrally formed with two mutually parallel guide bars 4, and the upper buckle seat 11 is provided with a guide groove 5 for inserting the guide bars 4, and the length direction of the guide bars 4 and the guide groove 5 is parallel to the connecting line between the upper fixing buckle 1 and the lower fixing buckle 2. The sliding cooperation between the guide bars 4 and the guide groove 5 guides the relative movement between the upper fixing buckle 1 and the lower fixing buckle 2.

[0045] Reference Figure 2 and Figure 3 The upper buckle cover 12 is integrally formed with an upper snap-on strip 6 on one side facing the lower buckle cover 22, and the lower buckle cover 22 is integrally formed with a lower snap-on strip 7 on one side facing the upper buckle cover 12. When the locking mechanism is in the locked state, the upper snap-on strip 6 and the lower snap-on strip 7 cooperate to realize the snapping of the quilt cover and the quilt core, thereby reducing the possibility of the quilt cover and the quilt core being forced to separate from between the upper buckle cover 12 and the lower buckle cover 22.

[0046] Reference Figure 2 and Figure 3 The locking mechanism includes a fixing pin 80 connected to the lower buckle seat 21, a cavity 81 opened on the side of the upper fixing buckle 1 facing the lower fixing buckle 2, an outer lock cylinder 82 connected to the cavity 81, and an inner lock cylinder 83 placed in the outer lock cylinder 82 (refer to Figure 4 ), the diameters of the inner locking cylinder 83 and the outer locking cylinder 82 gradually decrease along the direction from the upper fixing buckle 1 to the lower fixing buckle 2.

[0047] Reference Figure 4 The outer wall of the inner lock cylinder 83 is provided with three receiving openings 84 circumferentially, and the three receiving openings 84 are evenly distributed circumferentially around the axis of the inner lock cylinder 83, and the receiving openings 84 communicate with the inner cavity of the inner lock cylinder 83. A clamping member is provided in the space between the receiving openings 84 and the inner wall of the outer lock cylinder 82.

[0048] Reference Figure 4 When the locking mechanism is in a loose state, the gap between the three clamping members is smaller than the diameter of the fixing nail 80. When locking, the fixing nail 80 is inserted from the bottom end of the inner lock cylinder 83, and the fixing nail 80 drives the inner lock cylinder 83 to move in a direction away from the lower fixing buckle 2 through the clamping members.

[0049] Reference Figure 1 and Figure 4 After the fixing nail 80 is inserted into the inner lock cylinder 83 for a certain length, the user separates the upper fixing buckle 1 and the lower fixing buckle 2 in the reverse direction, and the fixing nail 80 pulls the inner lock cylinder 83 to move in the direction close to the lower fixing buckle 2 through the clamping piece. However, since the diameters of the inner lock cylinder 83 and the outer lock cylinder 82 gradually decrease from the upper fixing buckle 1 to the lower fixing buckle 2, the inner lock cylinder 83 can only move a very small amount, and the fixing nail 80 will also be clamped between the three clamping pieces.

[0050] Reference Figure 4 and Figure 5 The clamping member may be a ball 41, which is used to lock the fixing nail 80 in a point contact manner. The clamping member may also be a locking column 42, the axis of which is parallel to the line between the upper fixing buckle 1 and the lower fixing buckle 2, and the locking column 42 is used to clamp the fixing nail 80 in a line contact manner.

[0051] Reference Figure 1 and Figure 4 Since the reverse movement between the upper fixing buckle 1 and the lower fixing buckle 2 is very small, the clamping effect of the upper fixing buckle 1 and the lower fixing buckle 2 on the quilt cover and the quilt core is very small, and the upper fixing buckle 1 and the lower fixing buckle 2 can still clamp the quilt cover and the quilt core.

[0052] Reference Figure 3 and Figure 4The upper fixing buckle 1 is provided with a shifting opening 9, which is communicated with the cavity 81. A shifting block 10 is slidably disposed in the shifting opening 9. One end of the shifting block 10 extends into the cavity 81 and is located below the inner lock cylinder 83. A guide sleeve 13 is integrally formed at one end of the inner lock cylinder 83 facing the lower fixing buckle 2. The fixing pin 80 passes through the guide sleeve 13. A clearance opening 14 is provided at the position of the shifting block 10 relative to the fixing pin 80.

[0053] Reference Figure 3 and Figure 4 When the user needs to open the locking mechanism, the user manually moves the shift block 10, and the shift block 10 slides in the shift port 9, while driving the inner lock cylinder 83 to move in a direction away from the lower fixing buckle 2. The distance between the inner lock cylinder 83 and the outer lock cylinder 82 becomes larger, and the clamping member releases the fixing nail 80. At this time, the user can pull the upper fixing buckle 1 and the lower fixing buckle 2 in the opposite direction, so that the fixing nail 80 is separated from the inner lock cylinder 83.

[0054] Reference Figure 3 and Figure 4 A limit strip 15 is integrally formed on the two opposite side walls of the shift block 10, and the limit strip 15 is located in the cavity 81. One end of the limit strip 15 abuts against the side wall of the cavity 81 on the side opposite to the shift port 9, and the distance between the two limit strips 15 is smaller than the distance between the diagonals of the shift port 9.

[0055] Reference Figure 3 and Figure 4 The limiting strip 15 has a limiting effect on the shifting block 10, reducing the possibility of the shifting block 10 being separated from the upper fixing buckle 1. During installation, the user makes the line between the two limiting strips 15 parallel to the diagonal line of the shifting opening 9, inserts the shifting block 10 into the shifting opening 9, and then rotates it at a certain angle to achieve installation.

[0056] Reference Figure 3 and Figure 4 A positioning block 16 is integrally formed on the side wall of the upper buckle seat 11 and the upper buckle cover 12 relative to the cavity 81, and a semicircular mounting groove 161 is respectively opened on the opposite sides of the two positioning blocks 16. The diameter of the mounting groove 161 gradually decreases along the direction from the upper fixing buckle 1 to the lower fixing buckle 2, and the outer lock cylinder 82 is clamped in the mounting grooves 161 of the two positioning blocks 16 in the upper buckle seat 11 and the upper buckle cover 12.

[0057] Reference Figure 3 and Figure 4 An annular extension 821 is integrally formed on the outer wall of the outer lock cylinder 82 away from the end of the lower fixing buckle 2, and the two positioning blocks 16 are respectively provided with a card groove 162 at the position relative to the extension 821. When the outer lock cylinder 82 is clamped in the installation grooves 161 of the two positioning blocks 16, the extension 821 is stuck in the card groove 162, thereby reducing the possibility of the outer lock cylinder 82 moving in the cavity 81.

[0058] Reference Figure 3 and Figure 4 Three limiting strips 17 are integrally formed on the inner side wall of the inner lock cylinder 83. There is one limiting strip 17 on the inner side wall of the inner lock cylinder 83 between two adjacent accommodating openings 84. The distance between two adjacent limiting strips 17 is smaller than the diameter of the clamping member, thereby limiting the clamping member within the space between the accommodating opening 84 and the outer lock cylinder 82, reducing the possibility of the clamping member rolling into the inner lock cylinder 83 through the accommodating opening 84.

[0059] Reference Figure 3 and Figure 4 A compression spring 18 is provided in the cavity 81, one end of the compression spring 18 supports the top wall of the cavity 81, and the other end supports the end of the limit strip 17 away from the lower fixing buckle 2, and at the same time supports the inner wall of the inner lock cylinder 83. The compression spring 18 supports the inner lock cylinder 83, reducing the possibility that the inner lock cylinder 83 moves relative to the outer lock cylinder 82, resulting in the possibility of accidental loosening of the locking mechanism.

[0060] Reference Figure 2 and Figure 4 The lower buckle seat 21 is integrally formed with a plug-in column 19 at a position relative to the plug-in slot 3, and a plug-in hole 191 is coaxially formed on the plug-in column 19. The fixing nail 80 is arranged in an "L" shape, one end of the fixing nail 80 is inserted into the plug-in hole 191 and has an interference fit with the plug-in hole 191, and the nail body at the other end is coaxially arranged with the outer lock cylinder 82, the inner lock cylinder 83, and the guide sleeve 13.

[0061] Reference Figure 3 and Figure 4 The lower buckle cover 22 is integrally formed with a limiting cylinder 20 at a position relative to the plug-in column 19, and one end of the plug-in column 19 facing away from the lower buckle seat 21 is inserted into the limiting cylinder 20. The limiting cylinder 20 is provided with a clearance opening 23 at a position relative to the fixing pin 80. The limiting cylinder 20 has a limiting effect on the fixing pin 80, reducing the possibility of the fixing pin 80 being separated from the plug-in hole 191.

[0062] Reference Figure 6 The lower fixing buckle 2 is provided with a receiving cavity 24, in which an anthelmintic pill 25 is placed, and a cover 26 is bolted to the opening of the receiving cavity 24, and a plurality of vents 261 are provided on the cover 26. The anthelmintic pill 25 emits an odor and transmits it to the outside of the fixing device through the vents 261, thereby playing an anthelmintic role.

[0063] Reference Figure 6 Perfume and aromatherapy can also be placed in the accommodating cavity 24, so that the holder can be clamped at the air outlet of the car air conditioner as a car perfume.

[0064] The implementation principle of Example 1 is as follows: the user puts the quilt cover and the quilt core between the upper buckle cover 12 and the lower buckle cover 22, and when locking, the upper fixing buckle 1 and the lower fixing buckle 2 are brought close to each other, and the fixing nail 80 is inserted from the bottom end of the inner lock cylinder 83, and the fixing nail 80 drives the inner lock cylinder 83 to move in a direction away from the lower fixing buckle 2 through the clamping member. After the fixing nail 80 is inserted into the inner lock cylinder 83 for a certain length, the user separates the upper fixing buckle 1 and the lower fixing buckle 2 in the reverse direction, and the fixing nail 80 pulls the inner lock cylinder 83 to move in a direction close to the lower fixing buckle 2 through the clamping member. However, since the diameters of the inner lock cylinder 83 and the outer lock cylinder 82 gradually decrease from the upper fixing buckle 1 to the lower fixing buckle 2, the inner lock cylinder 83 can only move a very small amount, and the fixing nail 80 will also be clamped between the three clamping members.

[0065] When releasing the locking mechanism, the user manually moves the shift block 10, which slides in the shift port 9 and drives the inner lock cylinder 83 to move in a direction away from the lower fixing buckle 2. The distance between the inner lock cylinder 83 and the outer lock cylinder 82 becomes larger, and the clamping part releases the fixing nail 80. At this time, the user can pull the upper fixing buckle 1 and the lower fixing buckle 2 in the opposite direction to make the fixing nail 80 disengage from the inner lock cylinder 83.

[0066] Example 2

[0067] Reference Figure 7 and Fig. 9 The difference between this embodiment and embodiment 1 is that the locking mechanism includes a plug-in strip 27 integrally formed on the lower fixing buckle 2, at least one tooth groove 28 opened along one side of the length direction of the plug-in strip 27, a tooth cavity 29 opened on the upper fixing buckle 1 for inserting the plug-in strip 27, and a lock cavity 30 opened on the upper fixing buckle 1, and the lock cavity 30 is communicated with the tooth cavity 29.

[0068] Reference Figure 8 and Fig. 9 The locking mechanism also includes a positioning pin 31 integrally formed in the lock cavity 30, a rotating bar 32 rotatably sleeved on the positioning pin 31, teeth 33 integrally formed on the rotating bar 32 for inserting into the tooth groove 28, an elastic member placed in the lock cavity 30 for supporting the rotating bar 32, a blocking cover 34 bolted at the opening of the lock cavity 30, and a lock hole 35 opened on the blocking cover 34, a key 36 is provided in the lock hole 35, and a dial head 37 for driving the rotating bar 32 to rotate is integrally formed on the outer wall of the key 36.

[0069] Refer to the figure and Fig. 9 When the user locks the upper fixing buckle 1 and the lower fixing buckle 2, the plug-in strip 27 is inserted into the tooth cavity 29. The elastic member supports the rotating strip 32, so that the rotating strip 32 drives the teeth 33 to rotate. When the rotating strip 32 rotates a certain angle, the teeth 33 on the rotating strip 32 can be inserted into the tooth grooves 28 on the plug-in strip 27. At this time, the upper fixing buckle 1 and the lower fixing buckle 2 are in a locked state.

[0070] Reference Figure 8 and Fig. 9 The lock hole 35 is located at one end of the rotating bar 32 away from the positioning pin 31. When the user needs to unlock the upper fixing buckle 1 and the lower fixing buckle 2, the key 36 is inserted into the lock hole 35 and the key 36 is turned. The dial head 37 on the key 36 can drive the rotating bar 32 to rotate, and the rotating bar 32 drives the teeth 33 to disengage from the tooth groove 28, so that the upper fixing buckle 1 and the lower fixing buckle 2 can be separated.

[0071] Reference Figure 8 and Fig. 9 The lower fixing buckle 2 is integrally formed with a stop pin 38 for limiting the rotation bar 32 at a position relative to the lock cavity 30. The stop pin 38 is located on the side of the rotation bar 32 facing away from the elastic member. The stop pin 38 has a stop effect on the rotation bar 32, reducing the possibility that the rotation bar 32 rotates into the tooth cavity 29 when the locking mechanism is loose.

[0072] Reference Figure 8 and Fig. 9 The elastic member is a V-shaped spring sheet 39, one side of the spring sheet 39 supports the rotating bar 32, and the other side supports the inner wall of the lock cavity 30. Through the supporting effect of the spring sheet 39, the tooth 33 and the tooth groove 28 can be matched.

[0073] Reference Fig. 9 A fixing block 40 is integrally formed on the side wall of the lock cavity 30, and a V-shaped limiting groove 401 is formed on the fixing block 40 at a position relative to the V-shaped tip of the spring piece 39, and the V-shaped tip of the spring piece 39 is inserted into the limiting groove 401. The limiting groove 401 has a limiting effect on the spring piece 39, reducing the possibility of tilting and twisting of the spring piece 39 during deformation.

[0074] The implementation principle of Example 2 is as follows: when the user locks the upper fixing buckle 1 and the lower fixing buckle 2, the plug-in strip 27 is inserted into the tooth cavity 29, and the spring sheet 39 supports the rotating strip 32, so that the rotating strip 32 drives the teeth 33 to rotate, and the teeth 33 on the rotating strip 32 can be inserted into the tooth groove 28 on the plug-in strip 27, thereby achieving the locking of the upper fixing buckle 1 and the lower fixing buckle 2. When the user needs to unlock the upper fixing buckle 1 and the lower fixing buckle 2, the key 36 is inserted into the lock hole 35 and the key 36 is turned, and the dial head 37 on the key 36 can drive the rotating strip 32 to rotate, and the rotating strip 32 drives the teeth 33 to disengage from the tooth groove 28, so that the upper fixing buckle 1 and the lower fixing buckle 2 can be separated.

[0075] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
